7.1 pg_dump will not work against a 7.2 server.  In general there is
little hope of pg_dump version N working against server version > N;
it cannot know about later changes to the system catalog layout.
(And practically every major release has some.)

We have kept backwards compatibility since 7.0, though --- eg,
7.2 pg_dump still remembers how to get catalog info from 7.0 and
7.1 servers.
